ChatGPT 基于 OpenAI Images 2.6 模型支持文本和照片生成动画 GIF
原标题：ChatGPT can now turn text prompts and photos into animated GIFs with OpenAI's Images 2.6 model
ChatGPT 接入 OpenAI 新的 Images 2.6 模型，向所有网页、桌面和移动端 ChatGPT 与 Codex 用户推出 GIF 生成功能，可从文本提示词或上传照片生成动画，并调整速度或编辑单帧。据 The Verge 报道，示例显示角色跨帧保持可辨识，早前模型难以做到；面向开发者还发布了 GPT-Image-2.6 "Flare"（高效）和 "Sunburst"（高质量）两个 API 模型变体。OpenAI 称用户目前每周通过 ChatGPT 和 API 生成超过 40 亿张图像，比 9 月多出 10 亿。
为什么值得看原文给出 GIF 生成的使用方式、帧一致性表现和 API 两个模型变体，读者可以据此评估对图像生成工作流的影响。

ChatGPT can now create animated GIFs. The update is based on OpenAI's new Images 2.6 model and is rolling out to all ChatGPT and Codex users on web, desktop, and mobile apps, The Verge reports. Users can generate a GIF from a text prompt or uploaded photo, then adjust animation speed or edit individual frames.
As an example, OpenAI showed how the prompt "Can you make a gif of a cat dancing?" produces several slight variations of a character that are strung together flipbook-style into a GIF. The model's image consistency appears strong enough to keep the character recognizable across frames, while earlier models would likely have altered its look too much from one frame to the next for the trick to work.

Beyond GIFs, Images 2.6 is also meant to speed up image generation overall. For developers, OpenAI is also releasing the API models GPT-Image-2.6 "Flare" for efficient and "Sunburst" for higher-quality image generation. Both model variants were first introduced with Image 2.5. OpeneAI says users now generate well over four billion images per week via ChatGPT and the API, one billion more than in September.
